A Study of Silicon-based Oxide Fluorescent Nanofibers by Electrospinning

In this study, uniaxial electrospinning was used to prepare silicon-based oxide fluorescent nanofibers. Polyvinylpyrrolidone was mixed with alcohol and dimethylformamide, and tetraethoxysilane was used as the silicon source to prepare the precursor. Finally, yttrium nitrate, calcium nitrate, and europium nitrate are added to the solution for electrospinning,Use scanning electron microscope to investigate the surface morphology of nanofibers; thermogravimetric analyzer to measure weight loss at different temperatures and water drop angle tester to test hydrophilic and hydrophobic properties. After observing the surface morphology of the nanofibers with a scanning electron microscope, the average diameter of the as-spun fibers was 143 nm and the average diameter of the fibers after calcined at 600 °C was 147 nm.
